Re: Looking at XJ's
I would go with the 2000-01 4.0 XJs if you can afford the little extra cost. You end up with a way better ignition setup (coil on plug), slightly better intake design, an exhaust manifold that doesn't always crack, and nicer badges. Otherwise the '97 and up are the next best, stay away from the pre '91 Jeeps. (less power, terrible wiring and electronics)
Selec-trac came as an option on the Limiteds, Country's, Classics, and the older Laredos. It might have been on some sports but I don't think I have seen that combo. The Selec-trac only came behind the automatic with the 4.0.
I have had several XJs and my friends have or have had many others. They are very reliable and tend to run well over 200K miles with no major problems.
hope this helps,
